Description

Technical Field

[0001] This utility model relates to the field of winding technology, and in particular to winding equipment for processing OCA film rolls. Background Technology

[0002] Release film is a plastic film made by coating a release agent onto the surface of environmentally friendly materials such as PET, PE, and OPP release films, allowing it to exhibit extremely light and stable release force for various organic pressure-sensitive adhesives. Release films are produced in flat, long strips, so they need to be wound up. However, various release film winding devices on the market still have various problems.

[0003] Optical adhesive, also known as OCA optical release film, is a type of optical double-sided release film made by laminating a layer of release film on each of the top and bottom sides of optical acrylic adhesive without a substrate. OCA optical release film is usually used to bond transparent optical components, such as mobile phone touch panels, lenses and related components. In the production process of OCA optical release film, it is necessary to wind and unwind the OCA optical release film.

[0004] The above-mentioned device has the following defects: the winding and unwinding mechanism of OCA optical release film is prone to generating noise when the release film is pulled out, which affects the environment. The winding and unwinding mechanism exposes the OCA film to the outside, making it susceptible to contamination by surrounding processing dust, resulting in processing quality problems of the OCA film. Therefore, a winding device for OCA film roll processing is proposed to solve the above problems. Summary of the Invention

[0005] To overcome the above shortcomings, this utility model provides a winding device for OCA film roll processing, which aims to improve the problem in the prior art where the winding and unwinding mechanism exposes the OCA film to the outside, making the OCA film susceptible to contamination by surrounding processing dust.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a winding device for processing OCA film rolls, including a winding box, a motor fixedly connected to one outer wall of the winding box, a winding roller rotatably connected to the inner side wall of the winding box via bearings, a winding mechanism provided on the winding box, the winding mechanism sealing and straightening the winding opening to prevent deviation, an adjustment mechanism provided on the winding mechanism, the adjustment mechanism being used to straighten components to adapt to OCA film rolls of different widths, the winding mechanism including a film inlet, the film inlet fixedly connected to one outer wall of the winding box, a slot provided on the top outer wall of the film inlet, L-shaped plates slidably connected to the inner walls of both sides of the slot, an installation frame fixedly connected to one outer wall of the L-shaped plate, a brush fixedly connected to the inner side wall of the installation frame, a top plate snapped into the top inner wall of the installation frame, and a straightening plate slidably connected to the inner side wall of the top plate.

[0007] As a further description of the above technical solution: the adjustment mechanism includes a bidirectional threaded rod, which is rotatably connected to the inner wall of one side of the top plate via a bearing. An adjustment disc is fixedly connected to one end of the bidirectional threaded rod that passes through the top plate. A pin is slidably connected to the inner wall of the side of the adjustment disc. An adjustment hole is provided on the outer wall of one side of the top plate.

[0008] As a further description of the above technical solution: the mounting frame is slidably connected to the outer wall of one side of the film inlet, and the brush has two rows, which are respectively fixedly connected to the inner walls of the top and bottom sides of the mounting frame.

[0009] As a further description of the above technical solution: the width of the brush is adapted to the inner diameter of the film inlet, and the outer diameter of the film inlet is adapted to the outer diameter of the mounting frame.

[0010] As a further description of the above technical solution: there are two leveling plates, which are symmetrical to each other, and the inner side walls of the leveling plates are rotatably connected to the straightening rollers via bearings.

[0011] As a further description of the above technical solution: there are a number of adjustment holes, which are arranged in a ring on one side of the outer wall of the top plate, and the pin slides on the inner side wall of the adjustment hole.

[0012] As a further description of the above technical solution: the regular plate is threadedly connected to the bidirectional threaded rod, and a transparent window is fixedly connected to the inner wall of one side of the cover plate.

[0013] As a further description of the above technical solution: a cover plate is fixedly connected to one side of the outer wall of the winding box, a base is fixedly connected to the bottom outer wall of the winding box, and the winding roller is fixedly connected to the output end of the motor through a coupling.

[0014] This utility model has the following beneficial effects:

[0015] 1. In this utility model, by setting up a straightening plate, a straightening roller, a brush and other structures, the OCA film is straightened and cleaned during winding and the film is sealed after winding. This improves the winding and unwinding mechanism. Exposing the OCA film to the outside makes it susceptible to contamination by surrounding processing dust, which leads to processing quality problems of the OCA film.

[0016] 2. In this utility model, by setting up structures such as pins, adjustment holes, and adjustment discs, the width of the straightening component is adjusted and adapted when winding OCA films of different specifications. This improves the problem that the width of the straightening component is fixed, which leads to a mismatch between the width of the straightening plate and the film when winding different OAC films, causing the film to still be misaligned and damaged during winding.

A motor 3 is fixedly connected to one outer wall of the winding box 1, and a winding roller 5 is rotatably connected to the inner side wall of the winding box 1 via bearings. A winding mechanism 6 is provided on the winding box 1. The winding mechanism 6 seals the winding opening and straightens and prevents deviation. An adjustment mechanism 7 is provided on the winding mechanism 6. The adjustment mechanism 7 is used to straighten the components to adapt to OCA film rolls of different widths. The winding mechanism 6 includes a film inlet 60, which is fixedly connected to one outer wall of the winding box 1. A slot 61 is provided on the top outer wall of the membrane inlet 60. L-shaped plates 62 are slidably connected to the inner walls on both sides of the slot 61. An installation frame 63 is fixedly connected to one outer wall of the L-shaped plate 62. A brush 64 is fixedly connected to the inner wall of the side of the installation frame 63. The brush 64 seals the feed inlet and gently wipes and cleans the surface of the OCA membrane to reduce dust from affecting the processing of the OCA membrane. A top plate 65 is snapped onto the top inner wall of the installation frame 63. A leveling plate 66 is slidably connected to the inner wall of the side of the top plate 65. The leveling plate 66 is used to correct the deviation of the OCA membrane on both sides.

[0025] Reference Figure 2 - Figure 4 The mounting frame 63 is slidably connected to the outer wall of one side of the film inlet 60. There are two rows of brushes 64, which are fixedly connected to the inner walls of the top and bottom sides of the mounting frame 63. By setting two rows of brushes 64, the OCA film can be wiped on both sides at the same time. The width of the brushes 64 is adapted to the inner diameter of the film inlet 60, and the outer diameter of the film inlet 60 is adapted to the outer diameter of the mounting frame 63. There are two leveling plates 66, which are symmetrical to each other. The inner wall of the side of the leveling plate 66 is rotatably connected to the correction roller 67 through the bearing. The correction roller 67 reduces the friction between the two sides of the OCA film and the leveling plate 66. A cover plate 2 is fixedly connected to one side of the outer wall of the winding box 1, and a base 4 is fixedly connected to the bottom outer wall of the winding box 1. The winding roller 5 is fixedly connected to the output end of the motor 3 through a coupling.

[0026] Reference Figure 3 - Figure 4The adjustment mechanism 7 includes a bidirectional threaded rod 70, which is rotatably connected to the inner wall of one side of the top plate 65 via a bearing. The two straightening plates 66 are unfolded and adjusted by the bidirectional threaded rod 70. An adjustment plate 71 is fixedly connected to one end of the bidirectional threaded rod 70 that passes through the top plate 65. A pin 72 is slidably connected to the inner wall of the side of the adjustment plate 71. The pin 72 is used to limit the adjustment of the adjustment plate 71. Several adjustment holes 73 are provided on the outer wall of one side of the top plate 65. The adjustment holes 73 are arranged in a ring on the outer wall of one side of the top plate 65. The pin 72 is adjusted in multiple positions by the adjustment holes 73. The pin 72 slides on the inner wall of the side of the adjustment hole 73. The straightening plate 66 is threadedly connected to the bidirectional threaded rod 70. A transparent window 74 is fixedly connected to the inner wall of one side of the cover plate 2. The transparent window 74 allows personnel to observe the winding status of the OCA film in real time.

[0027] Working principle: The OAC film is wound up by the winding roller 5 inside the winding box 1. The OAC film passes through the brush 64, which cleans the outer walls of both sides of the OAC film. After the OAC film is taken into the winding box 1, the brush 64 automatically returns to its original position to seal the film inlet 60, preventing external dust from entering the collection box and affecting the OAC film. At the same time, during the winding process, the outer walls of both sides of the OAC film contact the alignment roller 67 on the straightening plate 66, so that the alignment roller 67 rotates with the OAC film during winding, preventing the OAC film from shifting and causing damage. In addition, according to the different winding widths of different OAC film specifications, the pin 72 is pulled out of the adjustment hole 73, and then the adjustment disc 71 is rotated to rotate the bidirectional threaded rod 70. The rotation of the bidirectional threaded rod 70 drives the two straightening plates 66 to move and adjust the spacing size according to the OAC width.

[0028] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
